The moths are stout bodied, hairy and sexually dimorphic, with fast-flying males and larger sluggish females. The larvae lie along twigs, to which they appress their dense, lateral hairs, effectively disguising their presence. The white, parchment-like cocoons are often spun among the foliage of the food plant.


Antennae bipectinate in both sexes; proboscis and maxillary palps absent; labial palps porrect, often beak-like with chaetosema-like sense organ on basal segment; epiphysis present in male, reduced or absent in female, tibial spurs very short, 0-2-2; fore wing without retinaculum, R 2 and R 3 stalked, without areole; hind wing without frenulum, humeral angle expanded, Sc fused with Rs near base, or connected to Rs by R 1 , Sc with 1 or more short branches to costa, CuP absent, 2 anal veins. Larva sometimes with dorsal protuberances, usually with dense secondary setae, sometimes on verrucae, or in pencils, or tufts, setae never branched, sometimes scale-like, crochets biordinal, simple. Pupa often hairy, epicranial suture present, sometimes with hooked anal setae; in stiff silken cocoon.


The family is world-wide in distribution, but absent from New Zealand.
